Quattro Eco 40mm LNB


Item: 3410


Specifically designed to meet the most updated requirements in the European satellite markets, this Universal Quattro LNB features low power consumption and high performance reception capabilities providing better system performance in heavy rain or weak signal levels.


It enables the reception of satellite signal from one satellite provides four fixed outputs for each band (H/H. H/L, V/H. V/L). It is ready for High Definition and 3D transmissions and delivers excellent Noise Figure, High Gain, Cross Polarization isolation and Phase noise performances. Manufactured to the highest industry quality standards and designed to meet strict specifications, this LNB is an ideal solution for satellite broadcast reception across Europe.

Frequently Asked Questions

What is a feedhorn?

The feedhorn is the part of a satellite dish system which gathers the reflected signal from the dish and focuses it towards the LNB.

What is an LNB?

An LNB - Low Noise Block (also called an LNC- Low Noise Converter), is used for communications (broadcast) satellite reception. The LNB is usually affixed either in or on the satellite dish.

What is an LNBF?

An LNBF is an LNB with an integrated feedhorn

What is a Monoblock LNB?

This design consists of two independent LNBs in a single case. The two LNBs can be automatically addressed with any DiSEqC 1.0 or higher receiver. In some cases they can also be addressed with ToneBurst / MiniDiSEqC. However, they are only available for satellites with a fixed 3 degree, 4.3 degree, 6 degree …spacing. In Europe, for example, there are monoblock single, twin and quad LNBs for the Ku band, which have a pre-defined spacing of 6 degrees (for Astra 1 / Hotbird , for example).

Why can I receive only one satellite with my Monoblock?

Monoblock LNBs are designed for a specific dish size, 80cm for example. If your dish is too small (70cm for example) or too wide (90cm for example) it is not possible to receive both satellites together. Please choose the dish size for which the monoblock LNB has been designed.
